CrowdFlower is a crowdsourcing service founded in 2009 by Lukas Biewald and Chris Van Pelt.[1] Founded as "Dolores Labs" in 2007.

History[edit]

Software[edit]

CrowdFlower has over 50 labor channel partners, among them CrowdGuru and TrialPay; their network is composed of more than 5 million contributors worldwide. A system of peer review also helps maintain high accuracy levels. It currently works with numerous Fortune 500 companies, including Microsoft, AT&T, Yahoo!, and eBay.[2] Currently, CrowdFlower offers eight SLA based enterprise solutions, as well as a self-service platform which allows clients to design and execute their own workflow. CrowdFlower also launched Real Time Foto Moderator, an image moderation tool for app developers and websites, on May 7, 2012.[3]

Applications[edit]

Researchers at the Harvard Tuberculosis Lab used CrowdFlower’s platform to identify drug-resistant TB cells. Contributors viewed cortex slides and were asked to identify TB cells. Typically this work would be given to graduate students, but the CrowdFlower was able to complete the task much faster without compromising accuracy.[4] After the 2010 Haiti earthquake CrowdFlower made it possible to route thousands of text messages to the proper aid workers, to get them translated quickly, and to ensure that the people sending the texts had the best chance of getting what they needed. Average time to translate, map, geocode, and categorize a text fell to less than two minutes.[5] CrowdFlower similarly helped relief efforts after the 2010 Pakistan floods.[6]

In 2009 CrowdFlower worked with Samasource to provide work for refugees in Kenya who completed microtasks; iPhone users donated their time by checking for accuracy through Give Work, an app.[7]
